TOY FOR THE PRODUCTION OF LOUD EXPLOSIONS.

SPECIFICATION forming part of Letters Patent No. 285,917, dated October2, 1883. Application iiled July 17, 1883. (ModeL) To all whom it mayconcern.-

Be it known that I, Bmzrnn OBER, a citizen of the Empire of Germany, anda resident of Urbana, county of Ohampaign, and State of Illinois, haveinvented certain new and useful Improvements in Toys for the Productionof Loud Explosions, which I call a Phonogen; and I do hereby declarethat the following is a full, clear, and exact description thereof, ref-IO erence being had to the accompanying drawings, and to the letters ofreference marked thereon, which form part of this specification.

The object of my invention is to furnish a toy which will take the placeof fire-crackers,

toy pistols, &c.

It consists of a sheet of paper or other suit able material folded asshown in Figure 1, or substantially so, with a handle attached, as shownin Fig. 2.

The sheets of paper or other material may be made of various sizes; butI have found the following to be the size best suited for the purposedesired-viz., twenty-four (24) inches long and fourteen (14) incheswide. Four 25 folds are first made along the lines 1 1 1 1, so that thepoint a will fall upon a, a upon a, a upon a, and 60' upon a. Then afold is made along the line 2 2, so that the two extreme angles willexactly coincide. The whole is then 0 folded along the line 3 3. Thelast fold is again opened, and the lines 2 and 3 on each side are madeto coincide, producing the folds on the lines 4 4 4 4. The sheet willnow have the form of a square, in which the fold along the line 3 willbe a diagonal and form a triangular body with a single folded edge onthe long side and four folded edges on each of the shorter sides. If,new, that portion of the triangle where the two extreme ends of the 0sheet fall upon each other be grasped by the hand and a rapid motion bemade through the air, holding the four edges in the direction of themotion, the air will be forced into the folds, and they will resume theangles along the lines 2 2. This produces a partial vacuum, and isaccompanied by a sharp explosive noise, similar to that produced by afirecracker. To facilitate the handling of the toy ahandle is attachedto the part where the two extreme angles of the sheet fall together. Thegreatest strain on the paper is on the end of the folds 2 2, and alsowhere the handle is attached. To strengthen these places a thin piece ofcloth or its equivalent is glued over each part mentioned. Besides thisa heavier piece of paper, or other material which will produce the sameresult, is glued over the part where the handle is attached, in order togive stability to this part.

Having therefore fully described my invention, what I claim is 1. A toyconsisting of a sheet of paper or other suitable material so folded asto produce an explosive sound when suddenly opened 7 by impact againstthe atmosphere, substan- 6 tially. as described.

2. A toy consisting of a sheet of paper or other suitable material ofthe size and proportion substantially as described, and folded, first,upon the lines 11 1 1; second, upon the 7 line 2 2; third, along theline 3 3; fourth, upon the lines 4 4 4 4:, having a handle, 5, attached,as shown, and adapted to be suddenly opened by impact against theatmosphere, thus producing an explosive sound, substantially as 7 andfor the purpose described.

I BERTHA OBER.
